This is a cast iron pot, the Staub Picot Cocotte Round 26cm, a deep pot with a capacity of 4.6L. Curry and soup carefully simmered in this pot are truly exquisite, bringing out the sweetness and tenderness of the ingredients. Although I haven't used it much, I have always applied olive oil after each use and taken good care of it. I am selling it because I am replacing it. - Brand: Staub - Color: Purple - Type: Two-handled pot - Material: Cast iron - Size: Approximately 26cm, 4.6L The dot-like protrusions on the bottom of the pot are present from the time of purchase and are due to the manufacturing process. Thank you for looking.
